Can you explain this more in detail? I have a Trek Equinox E9 and planned to run a Flo 60 front with 23mm Pro4 (Comp) and a disc cover in the rear.

Your Trek Equinox should be fine. The frame I was referring to was the blue triad. A 22mm rear tire works better than a 23mm tire on that frame.

Chris...are you saying that a Blue Triad EX should use a 700x22mm tire instead of a 700x23?

Earlier models had a very narrow chain stay where the tire ran. Wider tires (23mm) can have the tendency to rub the frame. In the case where I saw a 23mm tire rub, a 22mm tire worked. That said not all 23mm tires are the same and some could work. It really depends on the frame you have. You could try a couple options and see if they worked before settling on your tire. I'm sure your local bike shop wouldn't mind helping you figure that out if you are buying the tire from them.
